The one winery we visited down in NC, Dennis Vineyards, had wine slushies, they were very tasty.
And on another wine forum this recipe was posted to make your own wine ice cream
Red wine ice Cream
Makes about 1 quart
1 bottle fruity red wine, such as Beaujolais or Zinfandel
1 cup milk (I use skim)
1 cup sugar
1/2 cup pasteurized egg substitute (recommend "Egg Beaters")
1 cup whipping cream
1/2 tsp cinnamon
1 teaspoon vanilla extract
Pour wine into a saucepan and bring to a boil. Reduce heat and simmer until the wine is reduced to 1/2 cup, about 45 minutes. Remove from heat and allow to cool for 15 minutes.
In a medium mixing bowl, combine the sugar, milk, and egg substitute with an electric mixer on high for 1 minute. Gradually whisk in the reduced wine (don't add all at once, or the hot mixture may cause the eggs to set). Stir in the cream, cinnamon, and vanilla extract.
Put the mixing bowl in the refrigerator for 2-4 hours to chill. Process in an ice cream maker according to the manufacturer's instructions. It will look like soft serve ice cream at this point. For better texture, freeze for an additional 3-4 hours before serving.
